Differential Pressure Gauges

Differential pressure gauges measure the pressure difference between two points in an air or gas system. They are widely used to verify filter condition, monitor pressure drop across ducts and components, balance fans, and validate HVAC performance, cleanroom pressure cascades, and process equipment where stable ΔP is essential for efficiency, safety, and compliance.

This collection includes instruments covering a range of measurement spans, designed for clear readability, repeatable results, and dependable day-to-day operation. You’ll find models suited for hose connections to check filter and orifice pressure drop, as well as versions with easy-to-read scales or digital indication depending on the required resolution and workflow. Choose differential pressure gauges from PCE Instruments and Insize for maintenance, commissioning, and quality control tasks.

These tools are used by facility engineers, HVAC technicians, and QC specialists in industrial plants, laboratories, clean environments, and building services to support troubleshooting, measurement documentation, and preventive maintenance programs.
